I highly doubt I will have the time to try all the new research drug-games my children acquire access to. Better stick to first party Nintendo games-drugs.
In all seriousness, PBS kids apps on mobile go hard, work on any device, and are fairly educational while being easy to use and fun enough to hold attention while being completely FREE.
We've paid for ABC mouse but the whole fuckin thing reeks of slot machine pokie stimulus while the puzzles and games crash often. The only thing that 100% works all the time is the store to exchange your "tickets"
Abc mouse is the highest rated most teacher recommended app and it's fucking awful.
My 3 year old has gotten way more out of free software than any pay software that's littered with addictive BS.
I would recommend:
GCompris
Khan academy kids
Learn to read Duolingo ABC
PBS anything
France went to war in Afghanistan but not Iraq.
I served with French troops in Afghanistan amongst other NATO allies, Spanish and Australian.
